Chains symbolize the logical order of events. In this sense, the dream invites you to look at the past in order to solve present and future problems. If you dream that you are chained, however, it means that an internal aspect of yourself is being retained. You must set it free so it can express itself. If it is someone else who is chained, then you have to find out what aspect of the character that person represents. Similarly, if it is an animal, you have to ask yourself what aspect of your nature you are repressing. If it is a bull it might be your sexuality; if a dog, it may be your fury; and if it is an elephant it shows your inability to use your strength and wisdom. Dreaming that you are chained predicts you will be victim of injustice.

Body reactions during sleep
Most of us must have experienced hallucinations or night mares. When we experience such dreams we are unable to move or react. This stage is referred to as sleep paralysis. This type of dream occurs in between wakefulness and REM. As it occurs during the REM stage, it causes complete muscle weakness preventing the individual reacting to the dreams.
Some people can recognize dreams while sleeping; this type of dream is called lucid dreaming. Most of the people would have experienced this type of dream atleast once in their life. You can actually control these dreams. One of the popular dreams that most of us experience is as flying in the sky; you can try lucid dream by imagining your house beside the flying aid.
